  A zinc(II)/NHC system catalyzes the borylation of aryl halides with diboron (4) reagents in the presence of KOMe at rt. This transformation can be applied to a broad range of substrates with high functional group compatibility. Radical scavenger experiments do not support a radical-mediated process.

  photocatalytic borylation method that can effect borylation of a wide range of substrates, including strong C‒O bonds, remains elusive. Herein, we report a general, metal-free visible light-induced photocatalytic borylation platform that enables borylation of electron rich derivatives of phenols and anilines, chloroarenes, as well as other haloarenes. The reac-tion exhibits excellent functional group

  硼酸是中心重要的功能基序和合成前体。可见光诱导的硼酸化可以提供结构多样化的硼酸盐，但一种广泛有效的光催化硼酸化方法可以影响包括强 C-O 键在内的多种底物的硼化，仍然难以实现。在此，我们报告了一种通用的、无金属的可见光诱导光催化硼化平台，该平台能够对苯酚和苯胺、氯芳烃以及其他卤代芳烃的富电子衍生物进行硼化。该反应表现出优异的官能团耐受性，正如一系列结构复杂底物的硼化反应所证明的那样。值得注意的是，该反应是由吩噻嗪催化的，这是一种简单的有机光催化剂，MW< 200通过质子耦合电子转移机制介导了以前无法实现的可见光诱导的苯酚衍生物单电子还原，还原电位为~-3 V vs SCE。机理研究指出了光催化剂-碱相互作用的关键作用。
